'systematically-adjusted' originates from the combination of 'systematic' and 'adjusted'. 'Systematic' comes from the Greek word 'systēmatikos', meaning 'pertaining to a system', and 'adjusted' comes from the Old French 'ajuster', meaning 'to bring into line'.

'systematic' evolved from the Greek 'systēmatikos' through Latin 'systematicus', and 'adjusted' evolved from Old French 'ajuster' to Middle English 'ajusten'.

Initially, 'systematic' meant 'pertaining to a system', and 'adjusted' meant 'to bring into line'. Over time, 'systematically-adjusted' evolved to mean 'adjusted in a methodical and organized manner'.
